Definitions

  • the invention relates to an actuating device, in particular for the actuation of limited slip differentials Vehicles.
  • Such actuators are particularly in the Motor vehicle to support the drive and Brake systems use. They regularly include one Drive unit for driving an actuating shaft and a braking unit for braking the actuating shaft. about the actuating shaft can lock or lock a differential be switched off. The actual switching process takes over the drive unit.
  • the brake unit stops the actuating shaft in a predetermined position.
  • Such actuators are high To make demands.
  • the Withstand operating temperatures up to 200 ° C.
  • the Actuating shaft may also only be a relatively small one Subject to safe operation of the game To be able to guarantee limited slip differentials.
